a horror story centered around drugs, a passionate "love story", and a dramatic representation of how the Nancy Spungen spent her final days. It is probable to believe that two highly addicted heroin addicts don't have a clear enough mind to choose an appropriate potential life long partner, but instead at best choose someone who shares their addiction and off the wall antics.

Sid (of the sex pistols) and Nancy (retired hooker) will forever be a diabloical couple from the past, and are probabaly most famous because of how their lives ended.

The term "Sid and Nancy" is used to describe any couple that have become partners in crime, are badass, or seem to have an absurd mixture of violence and love.
